Application filed December 7, 1914. Serial No. 875,794 I To all whom itmay concern:

Be'it known that I, ARTHUR M. ROLAND, a citizen of the United States,residing at San Francisco, in the county'of San Francisco, State ofCalifornia, haveinvented a new. and useful Tire-Removing Clamp, of whichthe following is a specification in such full and clear terms as willenable those skilled in the art to construct and use the same.

7 This invention relates to a tool for removing tires from Wheels orrims and its objectis to produce a tool which can be disasse'm bled oreasily adjusted for different sized tiresas may be desired.

It will be understood by thoseskilled 'in the art that to enable theuser to remove many different types of pneumatic tire from the rims uponwhich they are mounted, that it is first necessary to squeeze the twoedges of the tire in contact with the rim together to release the tirefrom the rim, or to raise the tire out of the clencher rim.

, With this inventionit'is easy to force the two edges of thetire'together to release the tire from the rim and the device used forforcing the two parts of the rim together may be adjusted as may benecessary for diflerent thicknesses of tires.

Another object of the invention is to provide a tire removing devicewhich is capable of being so secured to the tire as to enable the tireto be pulled off the rim by simply pressing down on the handles withwhich the device is operated.

An embodiment of the invention is shown in the drawing in which the samereference numeral is applied to the same portion throughout, but I amaware that there are. many modifications thereof.

Figure 1 is a side elevation of the complete device assembled, Fig. 2'is an edge view of the frame, the operating 'mechanism being removedtherefrom, and Fig. 3 is an edge elevation of the operating handledetached from the frame.

. The numeral 1 represents a U shaped frame having an enlarged portion 2at one. end and carrying a tire bearing'head 3 at the other end, .said.head having a pin 4 thereon which projects into an openmg in the end ofthe frame 1. The end 2 is provided with an upwardly extending flange 5which flange forms a slide-way for the rack bar 6, said rack bar havingteeth 7 and a, tire bearing head 8 similar to the head 3.

Above the rack bar ,6'which also forms a handle there is\a handle 10pivoted to the frame by means of the screw stud 11, which handle carriesteeth 12 .and a flange 13 which bears on the side of the bar 6 assistmgin holding it in its proper position.

The number of teeth on the'handle 10 is such asto enable the handle tobe turned to a position, note Fig. 1, in which the bar 6 can be movedback and forth without interfering in any way with the teethon thehandle and when the bar has been pushed into contact with the tire thehandle may then-be turned to such a position on the rack bar as to forcethe heads 3 and 8 tightly into engagement therewithv and thereby squeezethe twoedges of the tire together and release them from the rim,whereupon tire free from the rim.-

It will be obvious that the device may be made in such sizes as isdeemed necessary.

An advantage of the. device lies in the fact that it may be easilydisassembledby simply removing the stud 11, whereupon 'the several partswill at once separate, the

the handle 10 having a .depression extendmg longitudinally thereof whichserves to lighten the handle and also to largement 14.

Having thus described my invention what the tool may be used as a leverto pry the receive the en- I claim as new and desire to'secure by Let- Iters Patent of the United States, is as follows, modifications withinthe scope of the claims being expressly reserved:

1. A device for removing tires comprising a U shaped clamp having aflanged guide way, a flanged segment gear pivotedto the clamp, a rackbar movable in the guide-way and held in place by said segment gearflange and the flange on the side of the guideway, a handle on the sideof the segment gear adapted to be moved into a position at the side ofand substantially parallel to the rack bar when it is pushed intocontact with a tire on said rack bar to hold the rack bar and handleonthe segment gear in a given position. 2. A device for removing tirescomprising a U shaped clamp having a head pivoted to one end and havinga flanged guide Way on the other end thereof, a rack bar carrying apivoted head slidable in said flanged guide Way, a segment gear havinga-fiange to assist in holding the rack bar in place in its fguide Way, ahandle connected with said segment gear and ofi'set from the sidethereof to move in a plane at the side of the rack bar, and a lug on therack bar adapted to bear in a depression extending rweaei HENRY B.LISTER A.
